Description
The 390-364334-0017 is a genuine Textron Aviation cover assembly aft avionics that encloses, provides access to, or streamlines part of the airframe. It is applicable to the Premier Model 390.
Because the 390-364334-0017 is an original-equipment (OEM) part sourced directly from Textron Aviation, it matches the exact specification and placement called out in the aircraft's type design and maintenance data — assurance a generic substitute cannot offer.
Because the Beechcraft Premier aircraft share extensive structure and hardware, a single part like this is often common across several variants.
A covering part like this is contoured to the structure, so the right one maintains both fit and the smooth external surface. On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front.
The factory part is built to the manufacturer's material and dimensional specification, so it installs as designed without the surprises a generic equivalent can bring. Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance.
Built by Beechcraft — the Wichita, Kansas manufacturer founded in 1932 and part of Textron Aviation since 2014 — this part carries a name long associated with rugged, capable aircraft. The Beechcraft Premier I was a clean-sheet, composite-fuselage light jet — the first jet Beechcraft designed in-house — supported today through Textron Aviation.
